1. 对列表进行乱序
通过 random.shuffle() 方法实现，直接对列表进行操作
>>> import random
>>> a = list(range(4))
>>> a
[0, 1, 2, 3]
>>> random.shuffle(a)
>>> a
[3, 0, 1, 2]
2. 获取指定范围的随机数
通过 random.uniform() 方法实现
>>> random.uniform(0,10)
2.3591479768289227
>>> random.uniform(9,10)
9.402797721231435
3. 将两个列表合并起来
通过 zip() 函数实现
>>> import random
>>> a = list(range(4))
>>> a
[2, 1, 0, 3]
>>> b = a.copy()
>>> random.shuffle(b)
>>> b
[2, 3, 0, 1] >>> list(zip(a,b))
[(2, 2), (1, 3), (0, 0), (3, 1)] >>> ba = list(zip(a,b))
>>> ba
[(2, 2), (1, 3), (0, 0), (3, 1)] >>> c
[2, 1, 0, 3]
>>> list(zip(ba, c))
[((2, 2), 2), ((1, 3), 1), ((0, 0), 0), ((3, 1), 3)]
4. 合并后的分离
通过 zip(*) 来实现
>>> ba
[(2, 2), (1, 3), (0, 0), (3, 1)]
>>> m, n = zip(*ba)
>>> m
(2, 1, 0, 3)
>>> n
(2, 3, 0, 1)
